Fig. 23–6.Response of the atmosphere to external excitation. a is the required response if the atmospheric S_2-tide is of gravitational origin; peak amplification is 100:1. b is derived from observed magnification and phase of M_2-tide.

Figures 1 and 2 are demonstrating both northern[1] and southern[2] hemisphere decay from a Dirac injection[3] of a test signal. The consequent effect is very close to perfectly linear, proportionality between pressure and effect of pressure over more than an order of magnitude of data variation (hence linear law). This seems to destroy IPCC claim of a non-simple law. Deviation is <1%

In addition the effect is a simple low pass filter on all kinds of atmospheric carbon dioxide. A later article might cover this in detail.

The curves bring out some interesting facts that deserve special consideration.For ordinary values of the humidity, the effective radiation has a maximum at 1 to 4 km. altitude. An increase of the humidity or a decrease of the temperaturegradient shifts this maximum to higher altitudes. The effective radiation gradientis consequently positive at low altitudes and negative at high altitudes. — A. Angstrom

Fig. 14 from paper 100 years ago by Anders Angstrom on LWIR emission. This shows families of curves grouped by two different lapse rates.

Physicist Dr Anders Angstrom was the son of physicist Dr Knut Anstrom (radiation instrument inventor) the son of physicist Dr Anders Angstrom after whom the wavelength unit the Angstrom is named. Confusion is understandable.

Hemisphere area coverage of snow and ice for land and ocean. Early data has been excluded after discovering an anomaly with early daily sea ice data, excluded is early part which is every other day data.[1]

This is an experimental first attempt at creating a hemisphere ice coverage dataset.

Why? I don’t like hidden information, want to see for myself and perhaps shed more light on whatever is going on.

As with sea ice data there is a distinct increase in the amplitude of the annual cycle in recent years. No attempt has been made to produce a more regular annual cycle exclusion.

If you are new to these videos expect a revealation, how air moves, clouds stream, bubble.

Clouds are sometimes on seveal levels moving in different directions: we are looking through circulation cells from above, warm air travelling to the Arctic to shed heat and cold air spilling back on it’s journey towards the equator.
